gradle bootRun 执行失败

Question

我正在尝试运行我的 spring 启动应用程序...当我将 eureka spring-cloud 插件添加到我的 gradle.build 文件时，这一切都开始了:

编译'org.springframework.cloud:spring-cloud-starter-eureka'

当我运行 "gradle bootRun" 时，我得到这个错误：

原因：java.io.IOException：无法运行编程"C:\Program Files\Java\jdk1.8.0_91\bin\java.exe"。 CreateProcess error=206，文件名太长。

我的build.gradle是：

import java.text.SimpleDateFormat

buildscript {
  ext {
    springBootVersion = '1.3.2.RELEASE'
    elasticSearchVersion = '2.2.0'
    groovyVersion = '2.4.5'
  }
  repositories {
    jcenter()
    mavenCentral()
  }
  dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")

    classpath 'com.github.ben-manes:gradle-versions-plugin:0.12.0'
    classpath 'org.kordamp.gradle:stats-gradle-plugin:0.1.5'
  }
}

def buildDate = new SimpleDateFormat('yyyyMMdd-hhmmss').format(new Date())

}

eclipse {
  classpath {
    containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
    containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
  }
}

springBoot {
  executable = true
}

我把插件拿出来，它执行正确。

我知道这应该是一个 Windows 长路径问题，但我该如何给出解决方案？

tim_yates 说得对，谢谢！

我从 link 中获取代码并将其粘贴到我的 build.gradle 文件的末尾，它像 gem 一样工作！

我添加的代码是：

task pathingJar(type: Jar) {
    dependsOn configurations.runtime
    appendix = 'pathing'

    doFirst {
        manifest {
            attributes "Class-Path": configurations.runtime.files.collect {
                it.toURL().toString().replaceFirst('/file:/+/', '/')
                }.join(' ')
        }
    }
}

bootRun {
    dependsOn pathingJar
    doFirst {
        classpath = files("$buildDir/classes/main", "$buildDir/resources/main", pathingJar.archivePath)
    }
}

注意：我从 link代码中添加了一些简单的引号 (') 以使其正常工作..
